* Rename --ca-file to --os-cacert (--ca-file deprecated for backward compatibility) * Add cacert to keystoneclient initialization to verify the keystone server certificate This aligns glanceclient with keystoneclient for option naming and the use of TLS for the keystone auth connection. It does not change the use of TLS/SSL for the glance connection. Change-Id: If8b05655aea5f3c62612d77bf947dd790f77eddf
